To be a good Muslim is to faithfully ascribe to and practice with full conviction the Principles of Iman and the Principles of Islam.
The Principles of Iman are :
1-Belief in No other God except Allah Subhanahu Wa Ta'ala
This belief is the most crucial, most important tenet of being a Muslim. The core of our being is this basic creed and testament to the Worship of the True God, Allahu Akbar, the Creator of all the Worlds and the Universes that exist within our visual comprehension and also the Unseen realms that are hidden to us.
This Belief is called Tawheed.
Tawheed is called Faith in Allah, the One and Only God Almighty.
Tawheed is divided into three categories of Faith and Belief.
First is Believing in the Oneness of Allah Subhanahu Wa Ta'ala in the sense of His Being the Only Creator, Preserver, Nourisher, Cherisher, Sustainer,etc.This part of Tawheed is called 'Tawheed Ar -Ruboobeeyah'.
Second is Acknowledging that only Allah alone is the One and True God who deserves to be worshipped and thus abstaining from worshipping or fearing any other being or thing! This knowledge is called 'Tawheed Al Ulooheeyah'
Third, having Faith and Belief in the Oneness of Allah's Asma 'ul Husna and Attributes @ Sifatullah! This Faith is called 'Tawheed Al Asmaa was Sifat'!
Tawheed is the utmost form of Faith that differentiates us Muslims from all the other beings in the world.
We are the ones who worship Allah ar Rahman ar Raheem as He deserves to be worshipped that is without attributing any other partners to Him and pray to Him earnestly all over this world practically each and every second of the passing second of Time immemorial!
We are Muslims who love Allah for no other sake than for His Redha' , we seek nothing else but His Rahma. His Mercy His Baraqah.
We, Muslims believe in the One Unique, Incomparable Rabb who has no son or partner and that none has the right to be worshipped but Allah alone!
He, Allahu Akbar is the true God and everything else is false!
He, Ar Rahman has the most magnificient names @ Asma 'ul Husna and sublime perfect attributes.
No one and Nothing shares His Divinity nor His Attributes.
In the Al Qur'an Al Kareem, Allah Subhanahu Wa Ta'ala describes Himself so clearly :
'Say , He is Allah the One. Allah, to Whom the creatures turn to for their needs. He begets not, nor was He begotten, and there is none whatsoever like Him!'
No one has the right to be invoked, supplicated, prayed to, or shown any act of worship except Allah Subhanahu Wa Ta'ala.
Who is there who can create and sustain life except for Allah Subhanahu Wa Ta'ala Who out of His Greatness has seen fit to create us and all the gazillions of Life here on Earth and in all the Universes which mankind are still discovering unseen, unheard of and unknown things and beings plus creatures great and small?
I will follow up with more after this, Insyaallah!
